PROBLEM TO BE SOLVED: To provide a table controller capable of removing the influence on machining precision of a workpiece due to a mounting inclination angle of a tilt table and improving machining precision when performing simultaneous multi-axis control machining.;SOLUTION: When an operation command of the tilt table is ON condition (A-axis operation condition) in an origin position shift part 10 (PLC, etc.), (step S1: Y), a calculation instruction signal of B-axis deviation angle α is turned ON (step S2). An A-axis angle θ is read in a B-axis deviation angle calculation part 9 based on this ON signal to calculate the B-axis deviation angle α (steps S12, S13). The calculated B-axis deviation angle α is written in the origin position shift part 10 (step S14). Moreover, the B-axis deviation angle α written from the B-axis deviation angle calculation part 9 is read in the origin position shift part 10 (step S3), and a position obtained by subtracting the angle from a current B-axis origin position is changed to a B-axis origin position (step S4).;COPYRIGHT: (C)2003,JPO
